<br />Quantitative sampling of reclaimed areas on Peabody Coal Company's Seneca II Mine was <br />undertaken in July 1990 by ESCO Associates to facilitate Peabody's continuing monitoring of <br />the progress of these areas in relation to revegetation performance standards. Methods, <br />sample areas, and sample sizes were those specified by Peabody. <br />METHODS <br />Reclamation Units and Samolino Locations <br />Reclamation sampling units are shown on Map 1, "1990 Revegetation Monitoring and Sampling <br />Location Map". The 1990 reclamation units include: Wadge mining areas reclaimed in 1983; <br />Wadge mining areas reclaimed in 1986; Wadge mining areas reclaimed in 1988; Wolf Creek <br />mining areas reclaimed in 1983; Wolf Creek mining areas reclaimed in 1986; Wolf Creek <br />mining areas reclaimed in 1988; as well as the Wadge Pasture Area and Wadge Pasture <br />• Comparison Area, both including areas reclaimed between 1978 and 1985. In addition to <br />sampling of the large 1986 Wadge area , a small Wadge mining area that was seeded in the <br />spring (1986 Wadge Spring) along with an equally small area on directly adjacent land that was <br />seeded at the normal time in the fall (1986 Wadge Fall) was sampled. Also, the Seneca II Mine <br />Mountain Brush and Sagebrush reference areas were sampled along with another area of <br />undisturbed Mountain Brush vegetation being examined as a potential reference area. The <br />latter area is refered to in this report as the "Native Study Area." <br />Within each reclamation unit identified by Peabody in their Scope of Work, the <br />Peabody-specified number of samples were located randomly using numbered grid cells and <br />random numbers taken from a random numbers table. These locations were placed as closely <br />as possible in the field. Final location of production quadrats was accomplished by a blind <br />throw; cover and density sample transects were located and oriented using a blind throw of a <br />meter stick. <br />Cover Samolino <br />Cover data were collected using a point intercept method in which data are tabulated as <br />• interceptions of a point (optically projected using aCover-point Model 31 with plant species, <br />soil, litter, or rock. The sample, taken at a randomly selected location, consisted of 50 <br />1 <br />
